Principles of Operation
The sample enters the Thermo Scientific Orion 2111XP sodium analyzer and passes through
the inlet valve, bypass/needle valve, inlet filter, pressure regulator, flow meter and into the
restrictor tubing. The sample then passes through the flow cell manifold into a reagent bottle and
through a diffusion tubing assembly where pH adjustment takes place. The pH-adjusted sample
then flows back through the manifold into the flow cell as air is introduced from the air pump to
ensure proper mixing and fast response. The sample then flows into an atmospheric drain via
the diverter valve.
Figure 1: 2111XP Schematic
The sensing electrode responds logarithmically to changes in the sodium ion concentration. This
response is described by the Nernst equation:
E = E0 + 2.3 (RT/nF) log (C/Ciso)
Where:
E = measured electrode potential, mV
E0= potential, when C equals Ciso, mV

R = ideal gas constant
T = temperature of sample, degrees K
n = valence of ionic species (+1 for sodium ion)
F = Faraday’s constant
C = effective sodium ion concentration (activity)
Ciso = concentration (activity) of sodium ion where potential E is temperature
independent (isopotential point)
The above equation indicates that the measured potential varies with both temperature and the
concentration of the ion of the interest. In order to eliminate error caused by fluctuations in
sample temperature, the 2111XP microprocessor constantly updates temperature corrections
from data supplied by the ATC probe.
From the Nernst equation, the theoretical response of a sodium ion selective electrode to a
ten-fold change in concentration at 25 °C is 59.16 mV. This is referred to as the electrode slope
(S). Most electrodes, however, do not exhibit a theoretical slope. Therefore, the analyzer is
calibrated to determine its actual value. Two standards are used to provide information
necessary for the microprocessor to compute the actual slope and E0 for use during sample
analysis.
In order to eliminate interference from hydrogen ions, which can become significant when
measuring low levels of sodium, the 2111XP analyzer raises the sample pH. This pH adjustment
is accomplished by the patented passive-diffusion process wherein the sample passes through
a length of tubing contained in the reagent bottle. The reagent diffuses through the tube wall and
mixes with the sample, which raises the sample pH.
Principles of Calibration
Calibration procedures for analytical instruments are important and must be performed carefully.
The calibration procedure used in the Thermo Scientific Orion 2111XP analyzer is a variation of
Double Known Addition (DKA) using advanced electrode and flow cell technology in
combination with the passive diffusion system. This method has the distinct advantages of being
fast, easy, and accurate.
Double Known Addition (DKA)
Before calibration begins, the diverter valve is pushed in to divert flow from the measure drain,
allowing the flow cell to fill.
At the beginning of the DKA calibration the actual concentration in the sample is unknown. The
analyzer measures the potential (Es) and stores this value in the microprocessor. A known
amount of standard 1 solution is added to the flow cell, which increases the concentration (Cs)
with a corresponding known amount (dc1). During this process, air is pumped into the flow cell,
1 | General Information

Section
thoroughly mixing sample and standard in a closed- loop system. The new potential (E1) is
measured and stored automatically when stability is reached. Adding standard 2, preferably 10
times more concentrated than standard 1, increases the concentration (dc2) in the sample
reservoir. Again, the new potential (E2) is measured and stored when the reading is stable. Now,
we have the following three unknowns:
Es = E0 + S(Ts/298.15) log (Cs/Ciso)
E1 =E
0 + S(T1/298.15) log [(Cs + dC1)/Ciso]
E2 =E
0 + S(T2/298.15) log [(Cs+ dC1+ dC2)/Ciso]
S is the Slope at 25 °C (298.15 K)
T is the temperature in Kelvin, measured when the potential E is measured.
Es, E1, E2 have been determined during the calibration procedure. The microprocessor solves
these three equations, to obtain the values of S and E0. The calibration result is stored for use
during online monitoring to convert the measured potential and temperature in the sample into
concentration values in either ppm or ppb.
When the calibration is complete the flow cell drains as the sample flow returns. The flow cell
volume returns to the measurement level. After allowing approximately 30 minutes for
concentrated calibration solution to be flushed from the system, the 2111XP analyzer can begin
sample measurement again.
In addition to Double Known Addition (DKA), the 2111XP analyzer also allows the operator the
ability to perform an offline calibration.

Offline Calibration
The offline calibration feature of the 2111XP analyzer allows the operator to adjust the analyzer
to values determined by alternate methods used in their laboratory such as elemental
spectroscopy and ion chromatography.
The offline calibration is essentially a one point calibration. To perform an offline calibration, a
sample is taken from the bypass of the analyzer; the sample concentration value is stored in
memory; the sample is analyzed by an alternate method of choice; the previously stored reading
is adjusted to the lab method result; and the analyzer is then returned to the analysis mode. The
term “offline calibration” refers only to the fact that a sample from 2111XP analyzer bypass is
taken “offline” for laboratory analysis; in fact, no downtime is experienced during the procedure
and the analyzer remains online throughout.

6. Carefully place the analyzer at a convenient location until proper installation can be
completed.
Mounting and Plumbing Instructions
Refer to the Appendix, Mounting Dimensions section.
WARNING: Do not connect power prior to the mounting and plumbing of the analyzer.
Recommendations
Select a site for the analyzer that allows it to be permanently bolted with ample height for
atmospheric drain operation. Be sure that there is ready access to the electronic controls,
calibration port and electrodes.
A clearance of 15 inch (about 40 cm) must be allowed above the flow cell calibration port.
Insert the pipet vertically (not angled) during the calibration.
The analyzer location must permit connections to a sample line, drain and AC power supply
and any connections for output devices.
The analyzer should be mounted as close to the sampling point as possible. This ensures
the fastest possible response to a changing sample condition. Refer to the Appendix,
Sample Conditions section.
For proper flow cell operation, the analyzer must be installed straight and level upon its
mounting location. Failure to level the analyzer may cause poor siphoning in the flow cell.

Instructions
1. Prepare the mounting holes. Carefully lift the analyzer and bolt it into place. Do not lift the
analyzer by holding on to any of the plumbing or fluid handling components.
2. Connect a waste line to the outlet of the analyzer, which is 3⁄4'' NPT male. The waste line
should be connected to a drain of sufficient capacity, 0.5 inch (1.27 cm) OD is
recommended.
3. Connect a sample line to the inlet of the analyzer, which is 1⁄4'' NPT female. It is
recommended that a shutoff valve be installed at the sampling point.
4. The analyzer must be mounted and leveled vertically for proper operation.
Sample Requirements
Additional information is listed in the Appendix, Specifications section.
Sample inlet connection – 1/4'' NPTF. If particulate matter is present in the sample,
pre-filtration is necessary. The 60 micron stainless steel filter located after inlet valve will remove
moderate amounts of particulates.
Flow rate – 40 mL/minute (nominal) for the Ammonia and DIPA Application Packages and 25
mL/minute (nominal) for the Cation/High Acid Application Package.
Pressure – 8 to 100 psig. Consult Technical Support for details on sample handling if the
pressure is outside of this range.
Temperature – Temperature must be between 5 and 45°C.
Sodium level – Sodium levels are read directly in ppb or ppm, when calibrated with Thermo
Scientific Orion sodium standards 1 and 2.
Sample alkalinity – Sample alkalinity should be less than 250 ppm CaCO3 equivalent. For
higher sample alkalinity, contact Technical Support.
